I'm a customer of Bungle1's, and I'm quite happy with his products and his service. He's Achilles over at DAZ, and makes the Head Sculpture Kits for V3, M3, David, SP, etc.

While many other similar products were not updated when the International Beauties version of V3 came out, the V3 Head Sculpture Kit was updated promptly. And unlike V3NewGen, it's easy to combine the new morphs with the standard ones. A lot of merchants could take lessons from Bungle1.
